JOHN NESTER, `OF PORTLAND, `OREGON.

Letters Patent No.` 97,795, dated December 14,A 1869.

INNERO'V'lEiIVIIEiNTA IN SCRIBE-HOOK.

The Schedule referred to in these Letters Patent and making part of the same` To all 'whom it may concern 4: Y

Be it-knowu that I, J 01am NEsTEn, of Portland, in the` county of Multnomah, and State of Oregon, have invented a new and improved Scribe-Hook lfor Weather-Boarding; `and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others'skilled in the'art to make and use the same, reference being had to the accompauying drawings, fo

`ruling part of this specification, in which- VFigure l represents a side vievv, partlyiu section, of

my improved weather-boarding hook. p

.Figure 2 is a plan view, partly in section, of the same.

f Similar letters of reference indicate corresponding parts. i

f This invention relates to certain improvements on the 'scribe-hook for'weather-boards for whichLetters' Patent No. 72,885 were granted to me on the 31st day of December, 1867.! v l p The present invention has for its object to make the instrument more generally useful, and better adaptable to the purposes for which it is intended, and

`to provide for au adjustable spur and marker.

The invention consists, first, in attaching the spur to a longitudinal pin or screw, which can be turned, so

p that the spur may be swung out ofthe way.'

`The invention also consists in making the marker adjustable on itsyfastening-pin, and in providing it with a V- shaped cutting-edge, so that it may swing on said pin, in accordance with the direction in which the slide is moved. i v

The invention consists, further, in providing springs p on the .main board-hook, for retaining the slide at eitherend.

j Figure 3 is a transverse section of the same, taken on the `plane ofthe line x x, fig. 1.

by a longitudinal screw, but works independent in the slotted part of the block A, and can be locked in any desired position by a thumb-screw, al. l v

The scale c, on the face of the block A, extendsv from the spul-.

Another ordinary inch-scale, f, is arranged ou the samelhlock, to enable the-same to be used as a rule. The spurc projects from a longitudinal pin, y, which can be turned so as to swing the spur out of the way,

into a slot provided in the block A.

In case the device isto be used for other purposes than for weather-boarding, the spur is carried out of the way.

The marker D is tted upon a pin, h, that has av head working in a slot on one side of tire block A.

' The marker is a knife, with a V-shaped cutting-edge.

'i is a pin, projecting from the pin h.. The' pin t lits through a segmental slot of a plate, j, that is clamped upon the piu h by a nut, 7c, or otherwise.

The marker is thus at liberty-to swing either way, so that its point l Vwill always swing back, when the device is drawn over a surface to be marked.

Assoon as the motion of the block A is reversed, the position of the marker will also be changed.

In the block A are arranged springs m fm, within the slot in which the pin h travels, and at the ends of such slot, so as to retain the marker at either end, to

rpreveniait from working loose'on the block.

Having thus described my invention,

What I claim as uew,aud desire to secure by Letters Patent, is-

1.` The marker D, when provided with the V- shaped `cutting-edge, in combination with the pin t', projecting from the pin h into the segmental slot ofthe plate j, all arranged to operate substantially as herein shown and described, a'nd for the purpose set forth.

2. The springs m m, in combination with the marking-device D h j, for the purpose of retaining the I marker, arranged as herein shown and described.

. The above specification of my invention, signed by me, this 25th day of May, 1869.
